Abstract

We discuss several different classes of selfdual Yang-Mills instantons in the backgrounds d = 4p dimensional spacetimes with Euclidean signature. One class of solutions are time-independent and spherically symmetric in d − 1 dimensions, and the other class are spherically symmetric in all d dimensions. Some the solutions in the former class are evaluated numerically, all the rest being given in closed form. An analytic proof of existence covering all numerically evaluated solutions is given. All instantons studied have finite action and vanishing energy momentum tensor and do not disturb the geometry.
